HOOD F Il-IOIILISIHIN'C-i AND 'BUFFING, lVIACHINES.

To all whom it may c'oficern.

Be it known that I, GUs'rAvE A. LEIMAN, a citizen of the United States, and resident of the borough of Bronx, in the city and State of New York, have invented a new and useful Improvement in Hoods of Polishing and Buffing Machines, of which the following is a specification.

This invention relates to an improvement 1.0 in hoods for polishing and bufling machines having novel means of applying light directly into the hood and upon the work being operated upon.

One of the objects is to provide a device which may be adjusted on the hood at diflerent angles with respect to the-operator and work.

Another object is to provide a device which is hinged to the hood and provided with a light holder arranged to be removed for cleaning and other purposes.

A practical embodiment of my invention is represented in the accompanying drawings in which, 7

Figure 1 represents a side 'view of one hood of a polishing and buffing machine with my improved device applied thereto, and a portion of the table being shown in section with a polishing head in position thereon.

Fig. 2 represents a front view of the same.

Fig. 3 represents a detail longitudinal section on a larger scale, taken in the plane of the line III of Fig. 2, looking in the direc tion of the arrow, and

Fig. 4 represents a horizontal section taken in the plane of the line IVIV of Fig. 1, on a larger scale. I

The table of the machine is denoted by 1 and has mounted thereon apolishing head 2 and a hood 3 having a mouth 4. The polishing head is provided with a spindle 5 having a bufling wheel 6 thereon, which is arranged in position in the mouth of the hood to deposit dust flying therefrom directly into the hood.

A shield 7 having side walls 8 is hinged at 9 to the upper part of the mouth 4 and arranged to swing toward and awayfrom the mouth. The walls 8 are provided with radial rims 10 which have a slight yielding movement maintained by a spring wire 11 secured in the rims, the tension of which rims serves to keep the walls 8 and a beaded rim 12 on the mouth of the hood in intimate contact. To further insure the shield against unintentional displacement, I provide the Spccificationof Lettersl'atentl Patented Apr. 19, 1 921.- Application filed March 6, ieiafs mino. 220,798. i I

walls with a'seriesof corrugations 13 {which coact with the beaded rim 12. The wire 11 is extended beyond the radial rims 10 on the walls 8 to limit the outward movement of the shield by its contact with the beaded mm 12.

The shield '7 has an opening 14 located centrally therethrough which is arranged to be covered by a light holder 15 having laterally extending tongues 16 which are arranged to slide in grooves 17 on the shield.

The holder 15 is provided with a socket 18 adapted to receive an incandescent lamp 19 e and having a switch 20 for controlling the lamp. The current is supplied to the lamp through a flexible cord 21 attached to a source of supply (not shown).

The inner wall of the holder 15 is furnished with a reflective surface to intensify the power, of the lamp in the hood.

The lamp 19 is protected from flying par-' ticles of dust and dirt by means of a wire mesh screen 22 secured to the shield in position to cover the opening 1%.

Thus it will be seen that the light from the lamp may be reflected into the hood, the angle of which is under the control of the operator and may be adjusted to the position best suited to the work.

It is evident that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention andhence I do not intend to belimited to the details shown and described exor sics.

cept as they may be specifically set forth in the claims.

What I claim is:

1. A hood for polishing and buffing machines having a shield pivoted thereon and provided with yielding side walls arranged to frictionally engage said hood for holding said shield in position with respect to the hood.

2. A hood for polishing and buihn'g machines having a mouth provided with a beaded rim, a shield pivoted at the upper side of the mouth and provided with yielding side walls arranged to frictionally engage said rim for holding said shield in position with respect to the hood.

8. A hood for polishing and bufling machines having a mouth provided with a beaded rim, a shield pivoted at the upper side of the mouth and provided with yielding side Walls, said walls having aseries of corrugations arranged to frictionally engage said rim for holding said'shield in position with respect to the hood.

4. The combination With ahood for'polishing and buffing machines having a shield pivoted thereon and'provided with yielding side Walls arrangedto frictionally engage said hood, said shield having" an opening therethrough, of a lamp and holder slidably connected to the shield in position to cover said 10 opening and direct light into the hood'anda screen covering the opening for protecting the lamb.

- In testimony, that claim the foregoing as my'invention, I have signed mynarne this 15
